Özet

We demonstrate that supercritical carbon dioxide deposition is a very effective technology for decorating multi-wall carbon nano-tubes with platinum nanoparticles with an average size as small as 2 nm and with a very narrow size distribution. Platinum loading can be controlled thermodynamically based on the adsorption isotherm of the platinum precursor between the supercritical carbon dioxide phase and the carbon nanotube phase.
